HYD RANT.

SPECIFICATION forming part of Letters Patent No. 313,265, dated March 3, 1885.

Application filed May 23, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. WARNER, of Des Moines, county of Polk, Iowa, have invented a new and Improved Hydrant,'of which the following is a full, clear, and exact description.

My invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be. had to the accompanying drawings, forming part of this specification, in which similar letters-of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of my improved hydrant. Fig. 2 is a sectional elevation of the lower portion on a larger scale on line w m, Fig. 3; and Fig. 3 is a horizontal section of Fig 2 online 3 y.

I make the valve for opening and closing the passage from the service-pipe a to the hy-.

drant-pipe b to consist of a stuffing-box, c, surrounding the hydrant-pipe b with packing-rings d of suitable flexible material above and below the mouth of the service-pipe a, to prevent the escape of the water along the pipe I), and fit the pipeb to slide up and down through said stuffing-box, and with an opening, 2, through the side near the lower end, which, when raised up to thelevel of thepipe (1, opens the passage for the flow of the water, and whenshi'i'ted down below said pipe at, closes said passage. This stuffing box is attached to the base-plate f of the hydrant-case m, below which I arrange a hollow cylinder, Z, closed at both ends and containing a piston, g, attached to the lower end of the hydrant-pipe b,and working up and down therein as the pipe b is shifted up or down to open and close the valve. ternal chamber, h, with passages 2' opening to the upper side, and a passage, j, opening into the lower end of pipe b,with a valve, is. closing downward thereon. The bottom of the cylinder is connected by a vent-pipe, a, with the hydrant-case m for admitting air under the piston to prevent the suction of a vacuum when raising the piston. The hydrant-pipe b is suspended from a cap, 0, of the top of the hydrant-case to be raised and lowered by a screw, p, which works in a tapped hole of the head (1 of said case, and is geared with a cranked pivot, s, swiveled to the elbow at the top of the pipe.

This piston has an in-- It will be seen that when the hydrant-pipe is raised up to bring opening 6 to pipe a, any I water in cylinder Z will be forced up through the opening'e and the hydrant-pipe until opening 6 passes above base-plate f, when the rest will be forced up through valve k, thus nearly emptying the cylinder, and When' the pipe a is cut off by shifting the hydrant-pipe down,the water remaining in the hydrant-pipe b will escape through opening e into the empty cylinder to empty the pipe and protect it from frost. The valve It prevents the water from flowing into the cylinder above the piston and exerting the pressure of the main downward thereon when the hydrant is open.

I prefer to make the opening from the pipe to to the hydrant-pipe b through a metallic ring, a, for a means ofprotecting said opening from the elastic packing-rings d, which might close it.

Any other desired approved device may be used for raising and lowering the hydrantp IiIaving thus described my invention, I claim as new and desire to secure by Letters Patcut-- 1. The combination of the metallic ring a with the pipes a and b, stufling-box c, and the elastic packing-rings d, said ring having an opening through it coincident with the pipe a, substantially as described.

2. The piston having a chamber h, passages z' and j. and valve k, in combination with cylinder Z and pipe b, having passage 6, and fitted in the stuffing-box 0, having the service-pipe a attached, substantially as described.

3. The combination of the adjusting-screw p, swiveled and cranked pivot s, and the shifting cap 0, with the hydrant-pipe b, and the hydrant-case on, having a head, q, pro-.

1), said pipe b being arranged in the stuffingbox 0, having the service-pipe a attached for opening and closing the water-passage, substantially as described. 1
